Objective:To investigate the expression of microRNA-324-5p (miR-324-5p) and transcription factor forkhead box C1 (FOXC1) in glioma and their relationship with the prognosis of patients.Methods:From March 2012 to March 2015, a total of 72 cases of glioma tissues were collected from glioma patients who were admitted to Chongqing Hygeia Tumor Hospital and the People's Hospital of Nanchuan in Chongqing, and 28 cases of normal human brain tissues resected in craniocerebral surgery were also collected. The expressions of miR-324-5p and FOXC1 mRNA were detected by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR), and the expression of FOXC1 protein was detected by immunohistochemistry. Pearson method was used to analyze the correlation between the expressions of miR-324-5p and FOXC1 in glioma tissues; Kaplan-Meier method was used to analyze the survival of patients with glioma; Cox regression analysis was used to analyze the risk factors affecting the prognosis of patients with glioma.Results:FOXC1 protein was mainly located in the cytoplasm of glioma, and its positive expression rate in glioma tissues was 81.94% (59/72), which was significantly higher than that in normal brain tissues [17.86% (5/28)], and the difference was statistically significant ( χ2 = 35.938, P<0.01). Compared with normal brain tissues, the expression of miR-324-5p was down-regulated in glioma tissues (0.62±0.19 vs. 0.98±0.02, t = 9.974, P < 0.05), and the expression of FOXC1 mRNA was up-regulated (1.41±0.29 vs. 0.99±0.02, t = 7.633, P < 0.05). The expressions of miR-324-5p and FOXC1 protein were correlated with the number of primary lesions, differentiation degree, TNM stage and lymph node metastasis of glioma (all P<0.05). Pearson analysis showed that the expressions of miR-324-5p and FOXC1 mRNA were negatively correlated ( r = -0.550, P<0.01). The 5-year overall survival rate of patients in miR-324-5p high-expression group was significantly higher than that of patients in miR-324-5p low-expression group (45.71% vs. 24.33%, χ2 = 6.531, P = 0.011), and the 5-year overall survival rate of patients in FOXC1 protein high-expression group was significantly lower than that of patients in FOXC1 protein low-expression group (30.41% vs. 42.34%, χ2 = 3.631, P = 0.047). Multivariate Cox regression analysis showed that low differentiation, TNM stage Ⅲ-Ⅳ, lymph node metastasis, low expression of miR-324-5p and high expression of FOXC1 protein were independent risk factors for prognosis of glioma patients (all P < 0.05). Conclusions:The expression of miR-324-5p is low and the expression of FOXC1 is high in glioma. They may be involved in the regulation of tumor differentiation and metastasis, and related to the poor prognosis of patients. They may be potential therapeutic targets for glioma.

Objective To set up the molecular cytobiological model of endogenous coagulation factor Ⅷ (FⅧ) re-expressing in human liver cells L02,and to study the regulation pathway and molecular basis of the re-expression of FⅧ in L02 cells activated by NO signal.Methods The L02 cells at logarithm growth phase were selected and randomly divided into blank control group and experimental group, inhibitor group and inhibitor control group;they were cultured for 0,12,24,36,48,and 60 h.Flow cytometry was used to detect the expression of human FⅧ protein in L02 cells after treated for 48 h.Griess experiment was performed to detect the levels of NO in L02 cells at different time points;the transcription levels of human FⅧ gene,iNOS gene,NF-κB1 gene and I-κB alpha gene were detected by RT-PCR method.Western blotting method was used to detect the expression levels of human phosphorylated I-kappaB (phosphorylated I-κB)in L02 cells.Results The results of flow cytometry showed that the expression of human L02 FⅧ protein was found after treated with L-arginine for 48 h. The Griess results showed that the levels of NO in L02 cells in experimental group were significantly increased at 3,6,12,and 24 h (P<0.05)and the levels of NO in blank control group,inhibitor group and inhibitor control group had no changes. The RT-PCR results showed that the transcription of human FⅧ mRNA in L02 cells was found in experimental group,but there was no transcription of human FⅧ mRNA in blank control group,inhibitor group and inhibitor control group;the transcription levels of iNOS,NF-κB1 and I-κB alphain experiment group were increased(P<0.05)and the transcription levels of these genes in blank control group,inhibitor group and inhibitor control group had no changes. The Western blotting results showed that after adding L-arginine the expression level of phosphorylated I-κB was significantly increased (P < 0.05 ), other groups had no such change. Conclusion L-arginine can activate the phosphorylation of I-κB by NO signal pathway to lead to the changes in the expression of human FⅧ gene promoter upstream regulatory-related transcription factors NF-κB to activate the expression of human FⅧ in human liver cells L02.

OBJECTIVETo examine the effect of ONO-AE3-208, an EP4 antagonist, on the formation of bone metastasis from prostate cancer in mice.

METHODSThirty-four 6-week old nude mice were divided into an experimental and a control group of equal number to be treated by intraperitoneal injection of ONO-AE3-208 and double distilled water, respectively. Then PC3/LUC cells were constructed by stably transfecting luciferin to prostate cancer PC3 cells and inoculated into the left ventricle of the mice to establish an animal model of systemic bone metastasis. The time of metastasis formation, photon tumor burdens, and changes of the survival curves after modeling were compared between the two groups of mice.

RESULTSAt 30 days after modeling, bioluminescence imaging analysis showed that the photon tumor burdens were significantly increased in a time-dependent manner in the control group in comparison with those in the experimental group (P < 0.01). The rate of metastasis formation was significantly higher in the former than in the latter (93.3% vs 33.3%, P < 0.001). The median time of metastasis formation was 29 d (95% CI 26.547 - 35.262) in the experimental animals as compared with 21 d (95% CI 17.213 -24.787) in the controls (P < 0.001).

CONCLUSIONEP4 antagonist ONO-AE3-208 can inhibit the formation of bone metastasis from prostate cancer in mice.

OBJECTIVETo study the effect and mechanism of Luohuo capsule (LHC) in treating essential hypertension of Phlegm-stasis blocking Collateral type.

METHODSNinety patients were randomly divided into two groups, the 60 patients in the treated group treated with LHC, and the 30 patients in the control group treated with Beijing Hypotension No. 0, the therapeutic course for both groups were 4 weeks. The changes of blood pressure, clinical symptoms, hemorrheologic parameters, plasma endothelin (ET), angiotensin II (Ang II), nitric oxide (NO) level before and after treatment were observed.

RESULTSThe total effective rate of clinical symptoms in the treated and the control group was 83.3% and 70.0% respectively, with no significant difference between them, but the degree of systolic pressure reducing in the former were better than those in the latter (P<0.05). The levels of hemorrheological parameters, plasma NO, ET and Ang II in the treated group were all improved (P<0.01 or P<0.05), but in the control group, improvement only showed in part of the hemorrheological parameters, ET and Ang II levels.

CONCLUSIONLHC has quite a promising effect in treating essential hypertension of Phlegm-stasis blocking Collateral type, the mechanism might be related with the improvement of hemorrheological parameters, increasing blood NO level and decreasing ET and Ang II levels.
